Application'filed February :16, 1912. Serial No. 677,974.

a citizen of the United States, residing in Hartford, in the county ofHartford and State of Connecticut, have invented certain. new and usefulImprovements in Combined- ZlIvpe-ll'riting and Computing Machines, ofwhich the following. is a specification.

This invention relates to a new and improved column selecting mechanismfor computing machines useful in such types as the Underwood Hansoncombined typewriting and computing machine, and is an improvement on theapplication of Fred erick A. l lart, No. 466,836, filed December 10,1908.

In the Underwood-Hanson.machine it has been common in the past tocontrol the se lection of the particular computing wheel in .aconiputinghead which-is to run up a number struck by one of the numeralkeys of the computing mechanism, so that the computing wheel selectedwill agree, in' its position, relative to the other computing wheels,with the denominational column in which the particular number is printedon the work sheeton the carriage, by causing the position of thecarriageto determine the picking up from its fellows, of the particularbar of a series, which actuates the computing wheel corresponding to thedenominational column being. printed.

This has been accomplishedby providing one or more tappets onthecarriage which, on the successive step-by-step movements of thecarriage, forced up one by one each of a series of jacks, which in turn,through associated linkages, raised the corresponding pin bars connectedto rotate the accordant computing wheels variable amounts according towhich particular one of a series of pins on each bar is depressed hv avaluating mechanism controlled from the numeral keys.

lVhilc the above system has its advantages, it is desired to presentiii-this application another way of doing the samething, so that the.carriage spring will only have to actuate the carriage itself and itsappurtenances.

It is therefore an object of this invention, hile still depending on thecarriage by its osition to sclectthe computing wheel accordant with thedenominational column beingwritten iii, to impose the actual work of theselection after it has been indicated bythe carriage, on some other partof the mechanism.

A further object of this invention is to impose on the numeral keystheactual work of shifting the computing-wheel-selecting mechanism asdetermined by the tappetcarried by the carriage;

Another feature of this invention is to provide means for rendering themechanism which actuates the jacks and pin bars in effective, when theplaten frame is shifted to write upper case characters, by disconnectingthis mechanism from the numeral keys.

A further feature of this invention is to enable the manualdisconnection at will of the mechanism for lifting the jacks and pinbars from the numeral keys, so as to permit the actuation of the numeralkeys in plain type-writing without operating anyof the associatedcomputing mechanism.

A still further feature of this invention is to provide new and improvedmeans enabling the'control of the comma and period locks which preventthe actuation of numeral keys at points where commasand periods shouldbe struck.

In the exemplification used to show the above objects, features andfurther features, the'carriage is provided with one or more tappets,according to the number of computing Zones desired, which are adjustableto any position relative to the carriage to control the computing zones,and are norm ally out of contact and connection with the series of jacksfor each computing'head. Each tappet, however, is movable. when inregister with any one of the jacks, to lift the same by mechanismoperable by any and all of the numeral keys on being struck. Thismechanism is shown to embody a linkage camming at one point against thetapocts to raise the same when in a computing zone. and connected atanother point to all the numeral keys so as to be operated thereby witha lost motion connection, however, so that while the operation of anyoneof the numeral keys will actuate the linkage, it will not disturb theother numeral keys. The

linkage is breakable either manually or by" the shifting of the platenframe to write upper case characters, at a point common to all thenumeral keys, so as to render the op erat'ive actuation of the linkageby the numeral keys impossible to effect the setting up of acomputation.

Provision is further made at points corspending to the comma and periodcolumns on the work sheet to hold the tappet in its raised positionafter having been forced up in this position in the previousdenominational columns, so as to actuate the associated jacks whichbring in play locking mechanism preventing the numeral keys from beingeffectively struck at these points, thus preventing an error andindicating to the typist that a. comma or period should be struck.

Other features and advantages will hereinafter appear.

teferring more particularly to the sepa, rate parts of this invention asembodied in the form shown in the drawings, 1 indicates numeral keys and2 character keys which are secured to key levers 3 and actuate type bars4, through the intermediary of bell cranks 5, to swing said type barsagainst the front side of a platen 6 mounted to rotate on a carriage 7.The carriage 7 is moved stepby-step at the actuation of each of the keysin the usual manner by means of a spring barrel 8 and under the controlof an escape ment mechanism indicated in general at 9. The carriage 7itself is mounted to run 'on rails 10, and is )ro*.*ided'with an innerearriage or platen frame 11, which supports the platen-6 in a movablemanner so that said platen can be moved bodily to change from lower toupper case characters. The platen frame 11 may be supported in anysuitable manner on the main carriage 7 as by being pivotally hungthereon by means of arms 12.

The inner carriage or platen frame 11 is also supported by one or morerollers 13 which rest on a shift rail 14; carried by a shifting frame 15pivotally mounted at 16 on the frame of the machine. The shifting frame15 is swung by one or more shift keys 17, which are each. provided withan arm 18 engaging the back side of the frame 15. It

will be readily seen by this mechanism that puting machine, and as isdescribed in the application of Frederick A. Hart, No. 466,836 andpatent to Hart No. 1,190.171 dated July 4, 1916. The lower bar 23 of theparticular elements of the valuating mechanism 19 operated by theassociated numeral key 1, will depress one of a series of index ing devces or pins 24 on the particular one of a series of bars 25 whichhappens to be raised above its fellows at' this instant. There is on'eof these bars 25 for each of a series of computing wheels 26, which inthe aggregate form a computing head. There may be one or more computingheads aecording to the charactera-nd numberof (701111.

they and their associated computing wheels. .26 correspond to someparticular denominational column being written on the work sheet on theplaten (5.

Inasmuch as the computing wheels 26 must be actuated in accordance withsomeparticular denominational column on the work sheet on the platen 6,it is found con-. venient to control the selectionof the par ticular.computing wheel to be actuated at any particularinstant from thecarriage by the position of the carriage. For this purpose there isadjustably mounted .on a rod 29, carried by the. carriage 7, one or moretappets 3O depending on, the number of computationsor computingzonesdesired in asingle line of writing.- The tappet 30, during, thestep-by-step movement of the care riage 7, will come successively intoregister with each one of a series of jacks 31 .lDlVOt, ally mountedintermediate theiroends on a stationary portion of the. frame of themachine. it will be noted in passing, however, that the t-appets 30 donot actually come in contact with the jacks 31 during the move? ment of.the carriage 7 of their own accord, but are normally located below andout of reach of the jacks 31, so that if desired the tappets 30 can passtreelybeneath the jacks 31 withoutoperat-ing the same either in aforward or return movement of the .car-. riage 7.

The jacks 31, when actuated, however, are raised at their forward :endsand depressed at their rearward ends, so as to push on the associatedone of a series of thrust links 32 connect-ed at their lower ends .toassociated linkages which are adapted to raise the accordantpin bars Itmay be pointed out that the linkages .33 are of a reversing ertransposing nature so that the jack 31 at the extreme left hand end, ofthe series will actuate the pin bar at the extreme right hand end of theseries, and vice versa, with the intermediate jacks and pin barsassociated in reverse order. Not all oi the jacks :in the series.however, are used to hit the pin bars. but certain of those, indicatedat 31;. operate thrust links to swing levers 36, whereby a lockin mechanism (not shown specifically herein but shown in said Hart. applicationand patent) is actuated through the intermediary of links 37 to preventthe c m )le e actuation of the numeral keys 1 'l --n once"? the tappets3O happens tobe in register with one of the jacks 3 L corresponding teadenominational. column onthe work sheet on the *arriage in which a commaor period should be struck; as between decimal and units, betweenhundreds and thousands, and thousands and millions.

Theindexing devices or pins 24:, when setup onthe bars 25, determine theextent of movement of said bars, and thus the extent ofrotation of thecomputing wheels he bars are actuated by a general operator 38 which hasa cross bar 39 adapted to engage all of the depressed pins during itsforward movement. The. bars are returned by a cross bar 40 engaging alug 41 provided on each bar in the manner as described in the abovementioned Hart application and pat out. The general operator 38 may beof any suitable character, and may be provided with a. rack 4C2 whichengages a pinion meshing with a segment gear 14: operated by anysuitable means such as a hand crank 45.

As has been stated above, the tappet or tappets 3O arenot capable inthemselves to actuate the jacks 31, and are more in the nature ofpassive means for selecting or indicating the particular one of thejacks to be actuated at any particular instant. lVe now come, therefore,to the means for applying thenecessary force to actuate the jacks 31 tocomplete the selection of a particular pin bar 25 to be raised, and thusthe selection of a particular computin wheel 26 to be actuated toaccumulate the number struck by a certain one of the numeral keys at acertain instant. The tappets are both slidingly and pivotally mounted onthe rod 29, so that they can be adjusted longitudinally thereof to anyposition relative to the carriage 7, so as to change the zone ofcomputing. These tappets 30 are each provided with a downwardlyextending lug *6, which, when in its lower position, will engage any oneof the grooves formed between teeth on a rack bar i7 which determinesthe position of the tappet 30 relative to the carriage 7. Thisconnection, however, while preventing movement of the tappets 30longitudinally of the rod 29,-does not prevent a swinging or oscillatingmovement of these tappets.

In order to obtain the oscillating or swinging movement of the tappet 30to raise the jacks 31, there is provided a bar 48 extending beneath allof the jacks 31 and 34;. H0 as to come in contact with a cam surface onthe lug 46 of the tappet 30, whereby the ta-ppet will be, forced up intoengagement with the jack 31, and also far enough to tilt the jack aboutits pivot the required amount to properly raise the associated bar 25.

The bar i8, which may be termed a universal bar in that it is common toall of the jacks 31 and B l, is supported by a pair of arms 50 securedto a rock shaft-51. These arms may be provided with oppositely facingcams 52 which will enable the tappet 46 to ride over the arms 50 to comein contact with the bar 48 when the carriage is moving in eitherdirection. Also secured tothe rock shaft 51 is an arm 53 which is usedto rock the shaft 51, and forms, with said shaft, the arms 50 and theuniversal bar 48, what might be termed a universal shifter or actuatorfor manipulating the jacks 31 through the intermediary of the tappet 30which forms a selecting or deter mining interponent.

The arm 53 is connected by a pin-andslotconnection 54 to a connectinglink 55, which is detachably connected at its front end to an arm 56 ofa universal bell crank 57. The universal bell crank 57 is provided witharms 58 individual to each of the numeral keys 1 to 9, and connectedthereto by means of links 59. It will be noted that between theuniversal bell crank 57 and each of the numeral keys 1 there is provideda lost motion connection, so that when one of the numeral keys actuatesthe bell crank, the others of the numeral keys will not in turn bedepressed by said bell crank. This is shown to consist in pin-andslotconnections 60 between the arms 58 and the links 59. From thisarrangement, it will be seen that the actual work necessary to raise thejacks 31 and actuate the connected mechanism, that is to say, lift theassociated bars 25, is imposed on the nu meral keys 1, so that they notonly determine the eXtent of rotation of the computing wheels 26 byactuating the proper elements of the valuating mechanism 19, but thatthey also complete the selection of the proper bars 25 and associatedcomputing wheels by raising the tappet 30 and the jacks 31.

Inasmuch as when the platen 6 and its frame are raised to write uppercase characters by an actuation of one of the shift keys- 17, it willnot be desirable to have the jacks 31 and the associated mechanismactuated at this time, because of the fact that numerals would not bestruck on the work sheet on the platen at this time. There is thereforeprovided means whereby the connec tion between the numeral keys 1 andthe tappet 30 can be interrupted, which means can be controlled by theshifting of the platen to write upper case characters. This isaccomplished by providing the connection between the universal shifterand the numeral keys 1, which may be termed with manner that while'thehook is in engagement with the pin, the movement of the numeral keyswill be positively transmitted to the tappet 30, but also so that thehook can be readily lifted from the pin to interrupt the connection.

The pin 62 may be in the nature of a set screw, as shown, engaging aslot in the arm 56 so that its position relative to the arm can bechanged to obtain a nicety of adjustment. The means for lifting the hook61 out of engagement with the pin 62 is shown to consist in adisconnector 63 secured to the shift rail 14, so as to raise the link 55when the platen frame and its platen are raised to their upper casewriting position. The disconnector is shown to include a plate 64secured to the shift rail 14 and depending therefrom in juxtaposition tothe link 55. Adjustably mounted on the plate 64, by means of one or morepin-and-slot connections 65, there is provided an adjustable guide 66having a guiding ear 67 formed by spaced ears 68 and 69 for. supportingand guiding the movement of the connecting link 55. The guide 66 ispreferably made of spring metal and provided with a handle 70, so thatit can be manually adjusted relatively to the plate 64, and when onceadjusted will positively hold its position until actually forced bymanual adjustment to a different position.

When the link 55 is raised from the position shown in Fig. 6 t0 theposition shown in Fig. 7, the bell crank 57 will naturally rock to theposition shown in Fig. 7 and it will therefore be necessary to force itback into engagement with the slot of the hook 61 when the link 55 isagain lowered. For this purpose there is provided on the link 55 a camlug 71 which is formed with an inclined edge engaging the pin 62 andadapted to force the pin into the slot of the hook 61 when the link 55is lowered. This therefore forms a manual and automatic means forconnecting and disconnecting the link 55 from the universal bell crank57, so that if desired the computing mechanism can be renderedinefiective by operatively' disconnecting the numeral keys from thecolumn selecting mechanism at this point.

It has been described how the tappet 30 is actuated by any one of thenumeral keys to raise one of the jacks 31. When, however, the tappet 30is in register with one of the jacks 34, which correspond to the commaand period columns of the number being written on the worksheet, it isdesirable that the numeral keys be locked so as to indicate that a commaor period key should 7 be depressed. Since the numeral keys cannot bytheir direct action cause the corresponding jack 34 to beactuated, othermeans must be provided to cause a positioning of the key-locking devicesunder control of one of the jacks 34. To accomplish this there isprovided a'selectingcletent or retainer 72 which has enlargements orears 73 located so as to engage a shoulder-'7 4! on the lug 46 of thetappet 3O and-hold it in its raised position after it has been raisedinthe do nominational column preceding the letter space column of a commaorperiod'.

The selecting detent 72 is shown in the form of a pivotally mounted pawlwith the enlargements or ears formed on the cross bar 75 thereof, andwithone arm '76 of the pawl extended so as to engage a spring 77 on eachone of the arms 50 of the universal shifte By this means, when theshifter tends to return after th pressure on the numeral key has beenreleased, the spring 77 wiil'engage the arm 78, holding the car 78 tightunder the shoulder 74, and also preventing the complete return of theuniversal bar f8 from beneath the 'tappet 30. hen the carriage, however,after the removal of the pressure on the comma or period key, which mustbe struck at this time, moves forward. it will carry the tappet 30 sothat the shoulder thereon will slip off from the end of the car 73,permitting the tappet 30 to fall out of engagement with the jacks. Inorucr that the tappet 30 may cam against the jacks 31 and 34, it may beprovided with acam tooth '78 which will cooperate succes sively withoppositely faced cam teeth 79 on the jacks 81 and 3%. The cam tooth 78may be pivotally mounted and held in its raised position by a spring 80,so that in case it should he accidentally held in its raised position,it will automatically slip by the teeth 79 during the return motion ofthe carriage without raising the jacks. The connection, iowever, of thistooth TS is such that during the letter feeding movement of the carriageit will be positively held against backward movement sojthat it willpositively lift the jacks 31 and 3% when the tappet 80 is raised to itsupper position. The connection between the numeral keys and the tappet30 is aided in its return to normal position, after the pressure on thenumeral keys has been removed, by spring 81 which is connected to thearm of the shifter and to a convenient member 82 on the frame.

inthe operation of the device it will be seen that when none of thenumeral keys are in their actuated position that all of the sableelements-4 of the typewriting mechsm are out of contactand disconnectedn all of the actuablc elements of the computing mechanism so that solong as no numeral key is actuated, the carriage can more back and forthand the other keys actuated without disturbing or interference fromthe'actuable elements of the computing mechanism. If, however, in theordinary operation of computing the carriage has been shifted in one wayor another to a position such that its printing point is in the zone ofprinting the numerals to be computed, then the tappet 30, if' thecomputing is carricdon at this instant with one oomputing:head-alone,will, if previously correctly adjusted relative to the carriage, come inregister with one-of the jacks 31' at the right of the set correspondingto this particular computing head. The tappet 30 will,-'=however, not bein actual contact with theja'ck '31, butmerely in a position to comein'contact'therewith. If the platen frame 11 is in its lower positioncorresponding to the writing of numerals with the numeral keys 1, andfurther, if the shifting guide 66 is in its lower position, as shown inFig. 10, then when one of the numeral keys 1 to 9 is struck, the t-appct30 will be raised through the connecting linkage embodying one of thelinks 59, the bell crank 57, the hook and the shifter engaging, by itsshifting bar atS, with the cam surface 46, so as to raise the front endof the apposite ack 31. This jack 31 will in turn, through theconnecting mechanism, raise the associated bar 25 above its fellows, sothat the pin 2% thereon, corresponding to the particular numeral keystruck, will be depressed below its fellows, soas to determine theextent of subsequentmovement of the bar 25 to carry up the numeralstruck on the accordant computing wheel 26 in the usual manner.

When the pressure on the particular numoral key, 1 actuated is removed,the parts will be returned to their normal position by the spring 81,permitting the tappet 30 to fall out of engagement w'th the actuatedjack 31, so that the corresponding bar 25 can fall to its depressedposition. The exception to this occurs, however, when the jackjustraised is located before one of the jacks 3% corresponding to a comma orperiod. In such a case, one of the ears 73 will be engaged by theshoulder 7st so that the tappet 30 will be held in its raisedposition'both by'the detent 72 and by the universal bar 48, whereby thecomma or period jack, on the movement of the carriage, which 7 takesplace on the removal of pressure from the actuated key, will be cammedup by the teeth '78 engaging the tooth 79 of the comma or period jack.hen this occurs, all of the numeral keys are locked against actuation,so that either a comma or period will be struck, thus bringing thecarriage to the next denominational column whenthe tappet 30 will havecleared the ear 73 which held it in its raised position so that it isfree to fall and permit the mechanism to return to its normal position.

If one ofthe shift keys 17 should be actuated so as to raise the platento an upper case writing position, then the link 55 will be raised bythe disconnector 63 so as to lift the hook 61 out of engagement with thepin 62, thereby interrupting the connection between the numeral keys andthe column selecting mechanism. In this condition of affairs, thenumeralkeys can be freely struck without lifting the tappet 30 to operate thejacks 31 and the connected mechanism. At other times when it is desiredto. do some typewriting work which mayrinvolve the use 01": the numeralkeys withoutcomputing, it is merelynecessary to force up the guide 66 bymeans of a knob-70 so as to manually raise the link out oficonnectionwith the bell crank 57. This also renders the control of the computingwheel selected by the typewriting mechanism inefiective.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
